Exploding wire light source was applied to obtain the organic dye laser.Threshold energies for Rhodamine-6G, Rhodamine-B, Na-fluorescein and Acridine-Red were 5J, 8J, 18J, and 35J, respectively.Experimental results are described concerning the liquid laser excitation with exploding wire.

It had long been known that uranyl salts have many sharp absorption bands when dissolved in various solvents1), 2). 3). Among these researches, in 1935 and 1939, Shibata et al.4). 5) showed that wave number of absorption hands of uranyl nitrate solution in acetone at lower temperature can be resolved with a general formula based on the theory of diatomic molecule. In this paper, the author wishes to report on the results gained when uranyl nitrate has been dissolved into many other organic solvents under varieties of temperature, for the purpose to examine the correct-ness of that formnla. Solvents used and the ranges of temperature (°C) estimated are as follows: water (ordinary temp.), urethane (<50°), acetamide (85°), methyl alcohol (15° and -70°), ethyl alcohol (15° and -70°), propyl alcohol (15° and -70°), ethyl ether (10° and -70°), ethyl acetate (-67°), methyl lactate (-40°). propyl valeriate (15°), ethyl acetoacetate (10° and -40°), acetophe-none (15°) and benzophenone (60°).

The evaporation method developed by Mandel' shtam and Zaidel is applied for the determination of impurity elements in uranium oxide.For the evaporation of impurity elements, most favorable sam-ple temperature, duration of heating, sample weight, and gap length between a collector electrode and a crucible are chosen.Calibration curves for the determination of Fe, Cr, Mn, Ni, Cu, B, Si, P and Cd are prepared.In the analyses of B and Cd, AgCl is added to uranium oxide (1%) as a carrier before evaporation and a d.c.arc excitation (10A) is used in the spectrographic procedure.Though the repeatability of analytical results is 10% or so for each element, the values determined for Fe and Ni are considerably deviated from the values obtained by the carrier-distillation method and chemical analysis.The evaporation rate is measured as a function of evaporation temperature for Sb, Fe and Cd by the use of radioactive tracers <SUP>124</SUP>Sb, <SUP>59</SUP>Fe and <SUP>115m</SUP>Cd respectively.

A simple controlled spark apparatus, based on the Maresca-Simons-Raiskij scheme, was constructed. In spite of its simplicity, experiments have given very high accuracy of analytical results. Several factors which may influence the reproducibility of the analytical results were investigated using Industrial Research Quantometer (A. R. L.) and ordinary photographic procedure. As a results, reproducibility of 2.4% expressed as standard deviations was obtained for the analysis of Ni in nickel-steel, wheseas 3.5% had obtained using high voltage spark supplied from High Precision Source Unit. This improvement in accuracy however, may mainly due to the difference of vaporization processes, although the stability of this apparatus had been clearly indicated by the stability of so-called arc to spark line ratio particularly.<BR>Low cost and easy maintenace are also the excellent features of this apparatus.

Application of Quantometer to routine analysis of low alloy steel is studied . As the operation was continued all day long, instrumental conditions became stabilized more and more with ever improving results. As for the standardization, once for every set of 200 samples seemed enough for accurate analysis. In the case of multisource spark-like condition, Quantometer is far more reliable than a rapid chemical analysis. At a high concentration range, chemical analysis gives higher accuracy than, quantometric analysis, but at a low concentration range, the reverse is the case. Owing to some particular phenomenon, prespark longer than 40 seconds was necessary for the analysis of nitriding steel. Molybdenum spectrum line of 2816A is affected by alminium spectrum line and can not be used;better results were obtained by the use of 2848A line of molybdenum . Chrominium lines is probably affected by the presence of aluminium, and analytical results were 24% too high on the average. This could possibly be lowered by renewing the graphite electrode .
